I am posting what I see ! Perhaps your interpretation is contradictory as it appears to be with the alsa devs. The point being is that what I can toggle with amixer and hardware mute on audigy or remote,  is not available in any mixer control! You can say they are contradictory however what I need is to change the mute/unmute behavior to conform to the hardware mute method such as I use amixer for. Amixer is the ONLY available unmute method when hardware mute is used on Audigy or remote.

I know the xbmc does a different mute because I programmed the xbmc mute on the remote . Even when deactivated or when not running xbmc the aforementioned hardware mute buttons behave differently than a software mute

I have also created situations where the hardware mute is off and the software mute is on and visa versa

These two statements are contradictory.

The remote's and device's mute buttons work automatically.  Unmuting
must be handled by some software that listens for these events.

Obviously, nothing is actually listening.  Why do you think that XMBC
is configured for this?

As far as I know, the only software that can handle the Audigy 2 NX's
remote events is LIRC: <https://help.ubuntu.com/community/LIRC>.
(Use driver "alsa_usb" and remote "RM-1500".)

Or just use "amixer -c1 cset numid=5 toggle".
